Description

Technical Field

[0001] This utility model relates to the field of ton bag unloading technology, and in particular to a ton bag unloading device with an auxiliary structure. Background Technology

[0002] Currently, there are roughly two types of unloading methods for ton bags on the market: One type has a sealed bottom without a discharge port. During unloading, a sharp object or other means is used to break the bottom of the ton bag, and the material inside is discharged by its own weight. The unloading process is accompanied by a beating action around the bag to clean the material out. This method generates dust during unloading, the damaged bags cannot be reused, and the beating device around the bag makes the overall size of the equipment relatively large, which is not conducive to operation in small spaces. The other type has a discharge port at the bottom of the ton bag. During unloading, the discharge port rope is manually untied and the discharge port is placed on the outside of the material cylinder, and the pressure plate tightens the discharge port. Although this method can reduce dust during unloading, the bags can be reused, and packaging costs are reduced, it still suffers from the common problem of being relatively large in size. Moreover, the action of untying the discharge port is time-consuming and requires manual operation, which is difficult to replace with machines.

[0003] For example, Chinese utility model (publication number CN218023267U) provides a rapid unloading device based on ton bags. This device includes a valve plate, unloading platform and unloading mechanism, valve plate unloading port, unloading structure, and other devices. This unloading device integrates the loose material handling equipment, reduces the overall size of the equipment, and simplifies the bag opening method by simplifying the unloading port valve plate structure, shortening the bag opening time, and providing the possibility for automated unloading.

[0004] However, through exploration, the inventors have discovered that this technical solution still has at least the following defects:

[0005] The unloading platform has an internal unloading structure that can move up and down. Generally, ton bags are stacked in one corner, but the device cannot move left and right to lift the ton bags. The ton bags need to be transported in batches to the designated location and then lifted for unloading by hand. This greatly restricts the unloading area, thus increasing the labor intensity and reducing work efficiency. Utility Model Content

[0006] The present invention aims to provide a ton bag unloading device with an auxiliary structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] It includes a bag-lifting machine and a unloading machine. The bag-lifting machine is connected to a servo motor and has a chute. A lead screw is rotatably connected to the inside of the chute. The output end of the servo motor is connected to the lead screw. A slider is threadedly connected to the lead screw. The slider is slidably connected to the chute. An electric hoist is fixedly connected to the slider. The electric hoist is connected to a rigid support. A cross-shaped hanger is connected to the rigid support. The unloading machine is connected to an automatic telescopic rod. The automatic telescopic rod is connected to a top plate. A cross-shaped steel knife is connected to the unloading machine. A screen is connected to the unloading machine. A discharge port is provided on the lower side of the unloading machine.

[0009] The unloading machine is connected to a dust removal device, which is used to clean up the dust.

[0010] Preferably, the dust removal device includes a dust removal box, which is fixedly connected to the unloading machine. The dust removal box is connected to a suction pipe and a filter screen. A suction fan is connected to the lower side wall of the dust removal box, and a ventilation opening is provided on the lower side of the dust removal box.

[0011] Preferably, the dust collection box is connected to a U-shaped positioning frame, and a sponge pad is connected to the inside of the U-shaped positioning frame.

[0012] Preferably, the dust collector is connected to a sealed door, and there is a drain outlet at the dust collector.

[0013] Preferably, there are two dust collection boxes, which are located on both sides of the unloading machine.

[0014] Preferably, the bag-lifting machine is connected to a fixed frame, and the fixed frame and the dust collection box are fixedly connected.

[0015] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0016] (1) This utility model uses a bag lifting machine to control the ton bags to enter the unloading machine for unloading. The servo motor drives the screw to rotate, so that the electric hoist can move left and right to lift a wide range of materials. The electric hoist drives the cross frame to lift and lower the ton bags, which can lift the ton bags for unloading. After unloading, the ton bags that need to be unloaded are removed and hung up to complete a cycle, which improves work efficiency and reduces the labor intensity of workers.

[0017] (2) By setting up dust collection boxes on both sides of the unloading machine, the dust generated by the impact force during unloading is absorbed into the dust collection bag, protecting the entire working environment and preventing dust from harming human health.

[0018] (3) By setting up a telescopic rod and a top plate, the top plate impacts the ton bag during unloading, allowing the damp material to be better separated from the ton bag to prevent sticking, and also preventing the material from accumulating on the side wall of the ton bag, thus improving the unloading efficiency.

[0019] (4) This utility model fixes the unloading position of the ton bag by setting a U-shaped positioning frame, which prevents the ton bag from shaking when the crane moves the ton bag, so that the bottom center area of ​​the ton bag can be accurately cut by the cross steel blade, thus speeding up the work efficiency.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0025] like Figures 1-3 The illustrated ton bag unloading device includes a bag lifting machine 1, an unloading machine 2, and a dust collection box 22. A servo motor 3 is fixedly connected to the upper side of the bag lifting machine 1. The bag lifting machine 1 has a slide 4, and a lead screw 6 is rotatably connected to the inner side of the slide 4. The output end of the servo motor 3 is connected to the lead screw 6. A slider 5 is threadedly connected to the lead screw 6, and the slider 5 is slidably connected to the slide 4. An electric hoist 7 is fixedly connected to the lower side of the slider 5. A rigid support 8 is connected to the lower side of the electric hoist 7 to increase the stability of the lifting operation. A cross-shaped hanger 9 is connected to the lower side of the unloading machine 2 for lifting the ton bag. An automatic telescopic rod 11 is fixedly connected to the upper side inside the unloading machine 2. The output end of the automatic telescopic rod 11 is connected to the top plate 12. A cross-shaped steel knife 16 is fixedly connected to the inner side of the unloading machine 2 for breaking open the ton bag for unloading. A screen 17 is fixedly connected to the lower side of the unloading machine 2. The screen 17 is located below the cross-shaped steel knife 16 to prevent the cut ton bag fibers from mixing with the material and being collected. The unloading machine 18 has a discharge port 18 on its lower side for conveying materials.

[0026] The unloading machine 2 is connected to a dust removal device for cleaning up dust. The dust removal device includes a dust collection box 22, which is fixedly connected to the unloading machine 2. A suction pipe 20 is fixedly connected to the upper side of the dust collection box 22, and a filter screen 23 is fixedly connected to the inner side of the dust collection box 22. The filter screen 23 filters and collects dust. A suction fan 14 is connected to the inner wall of the dust collection box 22. The filter screen 23 ensures the normal operation of the suction fan 14. A ventilation opening 19 is provided on the lower side of the dust collection box 22, and a sealing door 25 is rotatably connected to the outer wall of the dust collection box 22. A drain outlet is provided on the outer wall of the dust collection box 22, allowing wastewater to be discharged through the drain outlet by opening the sealing door 25. The dust on the filter screen 23 is cleaned. There are two dust collection boxes 22, which are located on the left and right sides of the unloading machine 2, respectively. The dust collection box 22 on the left side is connected to a U-shaped positioning frame 10 to control the positioning of the ton bag. The inner side of the U-shaped positioning frame 10 is connected to a sponge pad 21 to prevent excessive impact from damaging the frame and to increase friction so that the ton bag stops shaking more quickly. The dust collection box 22 on the left side is fixedly connected to the fixed frame 13 to prevent the machine from shifting during unloading. The bag hanging machine 1 is fixedly connected to the left side of the fixed frame 13, and the fixed frame 13 is fixedly connected to the left dust collection box 22 to prevent the device from shifting due to shaking during unloading.

[0027] The specific implementation process is as follows:

[0028] First, the servo motor 3 is started to drive the lead screw 6 to rotate. Due to the limiting effect of the slide groove 4 on the slider 5, the slider 5, which is threadedly connected to the lead screw 6, moves to the right. Then, the electric hoist 7 is started, causing the cross-shaped lifting frame 9 to move down above the ton bag. The worker fastens the strap on the ton bag onto the cross-shaped lifting frame 9, securing it with the locking block on the cross-shaped lifting frame 9. Then, the electric hoist 7 is started to lift the ton bag to the height above the unloading machine. At this time, the servo motor 3 reverses the lead screw 6, causing the slider 5, which is threadedly connected to the lead screw 6, to move to the left. When it reaches the U-shaped fixing frame 10, the servo motor stops, allowing the ton bag to move to the left. The bag is located inside the U-shaped frame 10. The sponge pad 21 prevents the ton bag from colliding with the U-shaped frame 10 and causing damage. The U-shaped frame 10 also helps the ton bag stop shaking more quickly. Then, the electric hoist 7 is activated, causing the cross-shaped hanger 9 to move downwards. The ton bag, bound to the cross-shaped hanger 9, moves into the unloading machine 2. Simultaneously, the dust collector 14 is activated, and the two dust collection boxes 22 use the suction pipes 20 to collect dust, preventing dust accumulated on the outside of the ton bag from falling into the unloading box 22 during the downward movement and affecting material quality. When the ton bag reaches the cross-shaped steel blade 16, the bottom center area of ​​the ton bag... As the small opening in the ton bag is lowered, its weight compresses it, ensuring the bottom of the ton bag evenly contacts the four steel blades. This tears a large opening at the bottom of the ton bag, allowing the material to fall rapidly. The falling material generates dust, which is then drawn inwards by the dust extraction fan 14 through the suction pipe 20 and expelled through the vent 19. This process absorbs the dust that flies upwards within the unloading machine 2, which is then filtered by the filter screen 23, protecting the dust extraction fan 14 for normal operation. When most of the material has leaked out, the automatic telescopic rod 11 is activated, causing the top plate 12 to impact the outside of the ton bag, releasing any adhering material and creases. The material falls rapidly. A screen 17 is installed on the lower side of the cross steel blade 16. The screen 17 can prevent the fibrous bag material cut by the cross steel blade 16 from contaminating the material and ensuring the quality of the material. The material will flow from top to bottom and be transported and collected through the discharge port 18. Then, the electric hoist 7 is started to pull the unloaded ton bag out of the unloading machine 2. Then, the servo motor 3 rotates and drives the lead screw 6 to rotate, so that the slider 5, which is slidably connected to the chute 6, moves to the right. Then, the electric hoist 7 transports the cross hanger 9 downward. The worker takes off the unloaded ton bag and hangs the ton bag that needs to be unloaded for the second unloading.
